Plasma Diagnostics and Technology of Materials
Master in Mathematical Engineering (Plan: 460 - Estudio: 88)

Coordinating teacher: SANCHEZ FERNANDEZ, LUIS RAUL

Department assigned to the subject: Physics Department

Type: Electives
ECTS Credits: 6.0 ECTS


Requirements (Subjects that are assumed to be known)
Basic knowledge of plasma physics and solid state physics including optical, electrical, and dielectric properties.
The purpose of this course is to introduce the students to the problem of nuclear fusion plasma diagnosis and the main issues for insulators operating in future fusion reactors, including the experimental procedures to simulate radiation damage due to fusion environment. The course includes the experimental techniques to measure optical, electrical and dielectric properties during irradiation of advanced insulators for fusion. The course will provide the student with a basic knowledge of plasma diagnostics, radiation damage processes in solids, experimental techniques to measure optical, electrical and dielectric properties during irradiation and the experimental procedures to simulate radiation damage due to fusion radiation environment.
